Specification of Letters Patent.

Serial No. 389,969.

To all whom it may concern:

Be it known that I, HENRY C. REYNOLDS, a citizen of the United States,and a resident of Portersville, in the county of Tulare and State ofCalifornia, have invented a new and useful Improvement in Trolleys, ofwhich the following is a full, clear, and exact description.

The purpose of the invention is to provide a simple, economic andreliable construction of trolley pole and head adapted especially foroverhead work, and which will be self-adjustable since the two saidparts will automatically so adjust themselves that the trolley head willstand almost horizontal on curves and overhead switches.

It is also a urpose of the invention to provide a pivota connectionbetween the head and the pole, wherein the head can turn laterally andfreely to a predetermined angle to the pole, and yet have limitedvertical movement when necessary without in any manner interfering withthe said lateral movement, since one member of the connecting mechanismwill not at any time unduly bind the other member within the prescribedlimitation of movement.

The invention consists in the novel construction and combination of theseveral parts, as will be hereinafter fully set forth and pointed out inthe claims.

Reference is to be had to the accompanyingdrawings forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a side elevation of the upper part of a car and a sideelevation of the 1mproved trolley head and pole ap lied; Fig. 2 is anenlarged side elevation of the trolley head and the end of the polecoupled thereto; Fig. 3 is a plan view-of the parts shown in Fig. 2;Fig. 4 is an enlarged longitudinal section through the trolley head anda plan view of the enteringend of the trolley poleand illustrates theposition of the parts when the head is at its greatest angle withreference to the pole; and Fig. 5 is a perspective view of the end ofthe trolley pole.

A represents the side of a trolley car, B the trolley pole appliedthereto, and O the trolley head. The trolley head is constructed withtwo forward vertical opposing cheek pieces 10 and 11, and between thesecheck pieces 10 5.3 and 11 the trolley wheel 12 is mounted to turnfreely upon a fixed pin 13 or equivalent means of support. At the rearof the central portion of the body of the said trolley head twohorizontal arms 14 and 1.5 are located, an upper and a lower arm, as isbest shown in Fig. 2, and the space between these upper and lower arms14 and 15 connects with a chamber 16, which chamber extends through theside portions of the said body, and in this chamber 16 a pinion 17 isvertically located, the said pinion being of the elongated type, and itsend. portions 18, which constitute trunnions, are preferably beveled, asis particularly illustrated in Fig. 2, and the said trunnions of thepinion 17 are suitably mounted in the aforesaid upper and lower arms 14and 15.

At the outer end of the trolley pole B, or that portion of the polewhich enters the space between the aforesaid up er and lower arms 14 and15, a segmenta head 19 is formed, which lies horizontally in the saidspace between the aforesaid arms 14 and 15, as is best shown in Fig. 4.The convexed or outer surface of the said head 19 is provided with teeth20, for engagement with the teeth on the pinion 17, and the said teeth20 are beveled, inclining usually from the top downward, as isillustrated in Fig. 2, and likewise in Fig. 5. The toothed surface 20 ofthe head 19 is eccentric with a pivot pin 21 that serves to pivot thetrolley pole B to the head O, as is clearly illustrated in Fig. 4, andthe inner faces of the upper and lower arms 14 and 15 are beveled inopposite directions from a point near their centers in an outwarddirection to the aforesaid chamber 16,. in which the pinion 17 ismounted to turn, therefore a substantially triangular space is providedbetween the upper and lower faces of the head 19 of the trolley pole andthe inner faces of the arms 14 and 15, as is clearly illustrated ,inFig. 2. This space 22 just referred to admits of the head having avertical movement to a limited extent relatively to the head, whenoccasion shall so require, without in any manner unduly jamming theteeth 20 of the trolley pole head on the teeth of the pinion 17; thusalso permitting the head. to freely turn laterally relatively to thetrolley pole B under all conditions.

The formation of the toothed surface 2-0 of the head 19 is such thatwhile at a point about centrally between the ends of said toothedsurface there is comparative freedom of touch between the teeth of thehead 19 and the teeth of the pinion, but as the outermost teeth arereached the contact becomes more pronounced, until when the extremeouter teeth have been reached at either end of the said head, theengagement between the head and the pinion will be such as to preventthe head from turning further in that direction.

This device is exceedingly simple and is reliable in operation, and itis evident that the head C can remain horizontal when turning a curve orpassing a switch, and that the trolley head can accommodate itselfautomatically to any curve no matter how pronounced.

Having thus described my invention, I claim as new and desire to secureby Letters Patent,

1. In a trolley, a trolley head, a pinion mounted thereon, a trolleypole mounted in the head, a toothed segment carried by the pole, whichsegment is in mesh with said pinion, the movement of the segmentrelatively to the pinion being limited in both directions by theformation of the toothed surface of the segment.

2. In a trolley, a trolley head, a pole on which the head is pivoted, apinion mounted in the head, and a segmental gear in mesh with the pinionand constituting a head for 30 the entering end of the pole.

3. In a trolley, a trolley head, a pole on which the head is pivoted.for lateral movement, a pinion mounted in the trolley head, and asegmental gear at the entering end of the trolley pole, the teethwhereof mesh with the said pinion and are eccentric to the pivot for thepole.

4. In a trolley, a trolley head, a pole 011 which the said head ismounted for lateral and for vertical movement, a pinion mounted in thetrolley head, and a segmental gear at the entering end of the trolleypole, the teeth whereof mesh with the said pinion and are eccentric tothe pivot of the pole, the i toothed surface of the said gear being alsogiven a downward and inward inclination from the upper portion of thegear.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
